SIGNAL DEVICE.

Specification of Letters Patent.

Patented Aug. 12, 1919.

Application filed August 7, 1918.- Serial No. 248,710.

- citizen of the United States, and resident of the city, county, andState of New York, and ALLEN L. HAMLIN, a citizen of the United States,and resident of East Orange, Essex county, New Jersey, have inventedcertain new and useful Improvements in Signal Devices, of which thefollowing is a specification.

This invention relates to a signal device and more particularly to amanual device which is adapted to be attached to the hand or the wristof the operator and is more esplppially designed for military useinsigna l.

Th5 object of the invention is to produce a simple and eflicient deviceof the class de scribed which may be worn without inconvenience to theoperator and without interfering with the use of the hand.

In carrying out the invention we provide a support which may bepreferably secured around the wrist of the operator and which isprovidedr'with an extension carrying a luminous disk at its outer end sothat the same is positioned in thepalm of the hand. The manner of usingthe same and its operation and detail construction and the novelfeatures thereof will be more fully described hereinafter. and definedand pointed out in the claims.

In the drawings accompanying this application we have illustrated apreferred embodiment of our invention, together with the details ofconstruction and arrangement of the several parts. In the drawings likeparts in the several views have been given the same reference numerals.

Figure 1 is a side elevation of the device.

Fig. 2 is a plan view and Fig. -3 an end view of the device shown inFig. 1.

Figs. 4; and 5 are enlarged detail views,

partly in section.

The support 1 is arranged to encircle the wrist of the operator and ispreferably constructed of a resilient material, such as spring-brass,which enables it to be readily slipped around the wrist and heldsecurely in place. Of course, it will be understood that a strap orother suitable means may be employed if desired.

The extension or arm 2 is pivotally attached to the support 1 andcarries a disk 3 at its outer end which contains a luminous material,such as radium paste, which may.

be held therein by means of a facet setting or otherwise, as may bedesired.

The extension or arm 2 is curved or formed to extend from the wristsupport It has been found that while different hands are difi'erent insize and shape that the portion or part, as well as the curvature, wherethe fleshy portion of the thumb joins the palm is approximately the sameand this fact enables us to so form the extension2 as to always positionthe disk 3 in the center of the palm. To cause the disk 3 to lie closeto the hand should the latter'be bent slightly back in signalin the endof the extension 2 which carries t e disk projects a substantialdistance across the projected area' of the band 1, as shown in Fig. 3. p

The disk 3 is pivotally hinged at the end of the arm 2 so that the samemay be sprung around the pivot either to present its luminous face 4outwardly away from the palm or turned inwardly against the palm so thatthe luminous face 4 is concealed and not exposed.

The pivotal attachment of the disk 3 may be formed by cutting andbending outwardly portions such as 5 and 6, as shown in Figs. 4 and 5.The end of the arm 2 is bent around to form a bearing, as shown at 7 and7 and a pin 8 is passed through the extensions 5 and 6 and the bent-overportions 7 and 7 which bent-over portions may extend into the openingsin the disk 3 formed by bending the ortions 5 and 6, shown in Figs. 4and 5. 'lhis permits of a very compact construction and allows the disk3 to lie substantially flat against the palm of the hand.

turned out as described and may be succes-.

sively covered and uncovered by closing and opening the fingers of thehand over the same and, when used in the dark, will cause successiveflashes of light and thus enable the same to be used for transmittingsignals or messages by the dot and dash code, or otherwise, as will bereadily understood.

When not in use the disk 3 may be turned with its luminous face towardthe palm of the hand, in which position no light is visible and, as thedisk and its support he close to the palm of the hand, the support orextension 2 following the curve of the fleshy part of the thumb where itjoins the palm, the use of the hand is not interfered with.

When a spring supportis used, such as shown at 1, it will be noted thatthe opening between the ends 9 and 10 (Fig. 3) is at one side of thecenter line of'the support. This is to position the ends 9 and 10 oneither side of the protruding bone in the wrist, which not only causesthe support to lie close to the wrist but also prevents it from turning.

It will thus be seen that a very simple device is provided which lendsitself to many uses but as many changes could be made in the details ofconstruction and many apparently widely different embodiments of ourinvention designed without departing from the scope thereof We intendthat all the matter contained in the above description or shown in theaccompanying drawings shall be interpreted as illustrative merely of anoperative embodiment of our invention and not in a limiting sense. 1

IV hat we claim and desire to secure by Letters Patent is 1. In a signaldevice, in combination, a

support adapted to be attached to the wristof the operator, an extensionattached to said support and projecting to a point to position the endthereof in the palm of the operators hand when the support is inposition upon the wrist of the operator, and a luminous member carriedby the end of said extension.

2. In a signal device, in combination, a support adapted to be attachedto the wrist of the operator, a resilient extension attached to saidsupport and projecting to a point to position the end thereof in thepalm of the operators hand when the support is in position upon'thewrist of the operator, and a-luminous member carried by the saidextension.

3. In a signal device, in combination, a support adapted to be attachedto the wrist ofthe operator,-an extension pivotall attached to saidsupport, and a luminous member carried by said extension and posi tionedin the palm of the hand of the op erator.

4. In a signal device, in combination, a support adapted to be attachedto the wrist of the operator, an' extension attached to said support andcurved in conformance to the curve of the fleshy part of the hand at thepoint where the thumb joins the palm of the hand and extending to thecenter of the palm, a luminous member carried by said extension andpositioned in the palm of the hand of the operator.

5. In a signal device, in combination, a resilient band forming asupport having an opening between its ends at one side of the centerline adapted to be positioned around the wrist of the operator with saidends positioned on either side of the protruding bone of the wrist, andan extension attached to said support, and a luminous member carried bysaid extension and positioned in the palm of the hand of the operator.

6. In a signal device, in combination, a support adapted to be attachedto the wrist of the operator, an extension attached to said support, anda luminous member hinged at the outer end of said extension andpositioned in the palm of the hand of the operator and adapted to beswung around its hinge to conceal or expose the luminous portion.

7. In a signal device, in combination, a band adapted to encircle thewrist of the op erator, a resilient metallic arm secured at one endthereto and projecting in a general direction at right angles thereto,said arm being bent first outwardly and then inwardly for a substantialdistance across the projected area of said wrist band, for the purposeset forth.

Signed at the city, county and State of New York, this 2d day of Aug,1918.
